Marin County Indoor Mask Mandate Update 12.15

We have confirmed that Marin County has been granted an exemption from CDPH’s indoor masking requirements on the condition that we reimpose our previous mask mandate.

Marin County’s local mask mandate, which had been lifted on November 2nd, will be restored effective December 15. This mandate requires all people – regardless of vaccination status – to cover their faces in indoor public places within Marin County. 

Like other Bay Area counties, Marin’s indoor mask mandate carves out limited exemptions for stable cohorts (groups of the same people) in select closed settings.

The settings where this applies include gyms, fitness centers, office settings, employee commuter vehicles, religious gatherings, and college classes.

In these limited settings, individuals are exempt from the indoor face-covering requirement if all of the following circumstances are satisfied:

  1. The host, employer, or organizer has verified that all individuals present are fully vaccinated (two weeks following a person’s second dose of a Pfizer or Moderna vaccine or the first dose of a Johnson & Johnson vaccine); and
  2. There are no more than 100 individuals present; and
  3. The host, employer, or organizer can control access to the setting, and the setting is not open to the general public; and
  4. The host, employer, or organizer maintains a list of individuals present.

Any gym, fitness center, office setting, commuter vehicle, religious gathering, or college class that is unable to fulfill all four of the above criteria must continue requiring masks for all people.

The exemption does not apply to all other public indoor environments, including bars, restaurants, retail establishments, etc. 

When in doubt, carry a mask with you and be prepared to comply with a business’s posted guidelines.
